How to Measure Your Foot
- Use a sheet of paper: Place it against a wall on a hard floor.
- Stand and mark: Heel lightly against the wall, mark your longest toe.
- Measure heel to toe: Measure the distance in cm.
- Measure both feet: Use the longer measurement.
- Wear your usual socks: If you’ll wear sports socks, measure with them on.
